1. Introduction

Digital or electronic evidence refers to information stored or transmitted in digital form, such as:

• Emails, WhatsApp chats
• CCTV footage
• Call records
• Computer files, databases
• Cloud storage data
• Mobile phone data

In modern trials, digital evidence is critical, but also highly vulnerable to tampering, manipulation, and fabrication. Therefore, legal systems (especially under the Indian Evidence Act, 1872) impose strict admissibility safeguards to ensure authenticity and reliability.

The key governing provisions in India are:

• Sections 65A and 65B of the Indian Evidence Act
• Judicial interpretation by the Supreme Court of India

2. Core Safeguards for Admissibility of Digital Evidence

(A) Section 65B Certificate Requirement (Most Important Safeguard)

A certificate under Section 65B(4) is generally mandatory for secondary electronic evidence.

It must certify:

• The device used (computer/mobile/CCTV system)
• The manner of production
• That the device was functioning properly
• That the copy is accurate and unaltered

👉 It acts as a guarantee of authenticity.

📌 Supreme Court has repeatedly held this is a condition precedent for admissibility.

(B) Original vs Secondary Electronic Evidence

• Original electronic record (e.g., data directly from server/device) → may be admissible directly
• Copied/printed/exported record → requires Section 65B certificate

(C) Integrity of Device and Chain of Custody

Courts require proof that:

• Evidence was not tampered with
• Proper forensic procedure was followed
• Chain of custody is maintained (who handled evidence and when)

(D) Forensic Examination Safeguards

• Hash values (digital fingerprinting of files)
• Forensic imaging of devices
• Expert verification under Section 45A (expert opinion on electronic evidence)

(E) Legal Relevance and Authenticity Test

Courts also examine:

• Relevance under Evidence Act
• Authenticity (source verification)
• Possibility of manipulation

(F) Judicial Scrutiny and Reliability Standard

Even if admissible, courts assess:

• Whether evidence is credible
• Whether it is corroborated
• Whether it has been illegally obtained

3. Important Case Laws on Digital Evidence (At least 6)

1. Anvar P.V. v. P.K. Basheer (2014)

Held:

• Section 65B is a complete code for electronic evidence
• Certificate under Section 65B(4) is mandatory for secondary electronic records

Significance:

• Landmark case establishing strict admissibility rule
• Overruled earlier relaxed approach

2. Shafhi Mohammad v. State of Himachal Pradesh (2018)

Held:

• Certificate requirement is not always mandatory
• Relaxation allowed if party does not control device

Significance:

• Created confusion by softening 65B requirement
• Later overruled

3. Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020)

Held:

• Reaffirmed Anvar P.V.
• Section 65B certificate is mandatory condition precedent
• Overruled Shafhi Mohammad and clarified law

Significance:

• Final authoritative position on digital evidence admissibility in India
• Restored strict compliance rule

4. Tomaso Bruno v. State of Uttar Pradesh (2015)

Held:

• Emphasized importance of CCTV and electronic evidence in modern trials
• However, incorrectly suggested secondary evidence flexibility

Significance:

• Recognized growing role of technology in investigation
• Later declared not good law on 65B issue

5. Sonu v. State of Haryana (2017)

Held:

• Objection to electronic evidence must be raised at proper stage
• Late objections to Section 65B compliance may be waived

Significance:

• Introduced procedural discipline in challenging digital evidence
• Prevents tactical delays in trial

6. State (NCT of Delhi) v. Navjot Sandhu (2005) (Parliament Attack Case)

Held:

• Electronic evidence could be admitted under general secondary evidence rules even without 65B certificate

Significance:

• Early liberal approach
• Later overruled by Anvar P.V.

7. P. Gopalkrishnan v. State of Kerala (2019)

Held:

• Accused has right to access electronic evidence relied upon by prosecution
• Fair trial includes access to electronic material

Significance:

• Strengthens procedural fairness and transparency in digital evidence use

4. Key Principles from Case Law (Combined Position)

From all landmark judgments, the following principles emerge:

1. Strict Admissibility Rule

• Section 65B certificate is generally mandatory (Anvar, Arjun Panditrao)

2. Electronic Evidence is Sensitive

• Courts treat it as easily manipulable → strict safeguards required

3. Fair Trial Rights Matter

• Accused must be allowed access and opportunity to challenge evidence

4. Chain of Custody is Essential

• Unbroken handling record strengthens reliability

5. Judicial Consistency Over Time

• Final settled law now favors strict compliance

5. Conclusion

Digital evidence is indispensable in modern litigation but inherently vulnerable to manipulation. Therefore, admissibility is controlled through strict safeguards, especially the Section 65B certification requirement, forensic verification, and judicial scrutiny.

The Indian judiciary has moved from a flexible approach (Navjot Sandhu) to a strict regime (Anvar P.V. and Arjun Panditrao), ensuring that only authentic and reliable electronic evidence is admitted in courts.
